Hyperentanglement-enhanced quantum illumination
Ashwith Varadaraj Prabhu, Baladitya Suri, C. M. Chandrashekar
In quantum illumination, the signal mode of light, entangled with an idler mode, is dispatched towards a suspected object bathed in thermal noise and the returning mode, along with…
Characterizing decoherence rates of a superconducting qubit by direct microwave scattering
Yong Lu, Andreas Bengtsson, Jonathan J. Burnett +8
We experimentally investigate a superconducting qubit coupled to the end of an open transmission line, in a regime where the qubit decay rates to the transmission line and to its o…
Towards phonon routing: Controlling propagating acoustic waves in the quantum regime
M K Ekström, T Aref, A Ask +5
We explore routing of propagating phonons in analogy with previous experiments on photons. Surface acoustic waves (SAWs) in the microwave regime are scattered by a superconducting…
Large collective Lamb shift of two distant superconducting artificial atoms
P. Y. Wen, K. -T. Lin, A. F. Kockum +9
Virtual photons can mediate interaction between atoms, resulting in an energy shift known as a collective Lamb shift. Observing the collective Lamb shift is challenging, since it c…
Nonexponential decay of a giant artificial atom
Gustav Andersson, Baladitya Suri, Lingzhen Guo +2
In quantum optics, light-matter interaction has conventionally been studied using small atoms interacting with electromagnetic fields with wavelength several orders of magnitude la…
